FIELD: agriculture.
SUBSTANCE: group of inventions relates to agricultural tools, in particular to a hydraulic control system having one hydraulic remote control. The hydraulic control device comprises a first hydraulic system for the transfer of weight to the tools for interaction with the soil, a second hydraulic system for controlling the folding and unfolding of the sections and the only hydraulic remote control made with the ability to control the operation of the first and second hydraulic systems. The hydraulic control system is characterized by the presence of the above-described hydraulic control unit. The agricultural implement comprises a tool bar having a fixed frame section made with the ability to be connected to a towing vehicle, and the first and second side sections pivotally connected to the opposite sides of the fixed frame section, a plurality of tools mounted on the tool bar, a hydraulic control system for controlling the movement of the tool bar. The hydraulic system comprises three groups of hydraulic cylinders and a hydraulic remote control made with the ability to control the operation of the first and second groups of the hydraulic cylinders.
EFFECT: hydraulic system with the simplicity of constructive implementation provides folding and unfolding of the side sections of the foldable agricultural implement, and lowering the tools for interaction with the soil.
